Being a little controversial, there is a problem with the idea "facts".
As is demonstrated in cc different people claim different things as facts and discount
others as merely opinions or allegories.
So I would rather talk about the validity of models, which make various assumptions,
and testing those assumptions.
I say this merely because to my cost I realise we are completely built upon our asssumptions.
We have fellowship here because we have faith in Christ.
This assumes a lot about what scripture is, and history for that matter.
But christianity has had a history of wanting to define absolutes of behaviour, morality, history,
origins, and has been shown to be mistaken about quite a few secondary assumptions or facts.
Let me put this into real context. You and I assume gravity works for everyone in our lives.
We can show its effect, but we as a culture have no clue what it really is. Tomorrow we could
find a place where gravity does not work, but we have not yet, so we assume there is no
place where gravity does not exist.
So the fact of gravity is bounded by this assumption. It is humbling to know our limitations, and
know all our opinions are equally as solid or fragile as this, but this is real value, but with context.
